pls. help in my program

can somebody help me?Im a 1st yr. college student taking up IT. And we have this case study that I cant seem to answer on my own so I decided to join daniweb. The program that Im referring to is a slum book simulating program.

EDIT-To edit the data that has been inputted, SEARCH-To search a certain data entered into the program. LIST-the program will list all the data you have inputted. and EXIT to exit the program.
